Abstract
The population development of Czechia in 2020 was significantly affected by the COVID-19 epidemic. Epidemiological measures or the pandemic itself were reflected in almost all monitored demographic processes, and in many cases long-term trends were interrupted.
In addition, existing minimums or maximums were rewritten within the period of the last ten years. The article focuses on the main demographic processes, namely births, deaths, marriages, divorces and migration.
The beginning of the examined period is the year 2011, in which the census took place, and then the following years, especially the period 2015-2020.
